Hemoaccess site infection.

Infectious complications involving a hemoaccess graft or fistula are a significant cause of morbidity in patients on chronic hemodialysis. A review of 274 consecutive hemoaccess procedures identified 28 infections (an incidence of 10 per cent). Infections occurred in 27 polytetrafluoroethylene (PTFE) grafts. The predominant organism was Staphylococcus aureus. Partial excision resolved 14 of the 27 graft infections. The remaining 13 required complete removal. Surgical management required six arterial ligations and seven autogenous reconstructions. No limb ischemia or mortality was directly attributable to these procedures. One infection occurred in 48 autogenous fistulas (an incidence of 2 per cent). Although partial removal of an infected prosthesis was often sufficient, brachial artery ligation was well tolerated when required to control anastomotic infection.
